Yokomo have introduced the new Racing Performer M3 series of electric 540-class competition brushless motors. Of an all-new design the motor features a redesigned stator, magnet and rotor for an optimised balance between RPM and torque with Yokomo’s top drivers Naoki Akiyama and Christopher Krapp being responsible for the fine-tuning of the overall package. The M3 series is available in 3.5T to 8.5T modified and 13.5T, 17.5T and 21.5T stock windings from April on.
Scorpion’s RS-3420 21.5T ETS electric brushless motor builds on the proven RS-3420 series modified and stock motors for exceptional performance and drivability. It features a 12.5mm rotor with patented screw-type surface for maximum torque and low running temperatures while a built-in cooling fan further reduces internal heat built-up. The can’s heatsink design offers up to 200 percent more cooling surface compared to plain can motors while a special design allows to maximise the copper fill of the windings. The motor, that is the hand-out motor for the Formula class of the Euro Touring Series, comes with special ETS markings for easy identification and it is available now.
Coming from Factory RC is the ROAR motor tech plate. This go/no go tech plate allows for quick inspection of any ROAR-approved motor for physical dimension requirements. The plate is machined from 2.25mm carbon look plate to the maximum tolerances allowed by ROAR. This allows the individual inspecting motors for legality to use a non magnetic tool to inspect the rotor and can for dimensions to assure legal racing. The rotor can be inspected using the length and diameter slot which also inspects for the 7.00mm internal OD shaft. There is also a pass through hole for the rotor body as well. Notches help to inspect the can diameter and length, as well as the 14.5mm “plug” go/no go gauge for the can/stack. This leaves only the stack length for inspection with a pair of digital callipers to finalise inspection which is easy to do since the stack is not magnetic. All measurements are clearly marked and the plate has so far been successfully used at various races.
Coming from Reedy is the Sonic 540-M3 25.5T ROAR spec brushless motor. Built to meet ROAR’s unique guidelines for 25.5 turn motors used in Formula and VTA racing classes, the motor’s resistance measures at the minimum legal value and it shares the same features list as the rest of the 540-M3 line. The M3 series utilises CNC-machined 3-piece cans, aluminium end caps, low-resistance, silver-plated solder tabs, optimised air cooling and dual precision ball bearings.
Hobbywing have introduced the QuicRun 3650 SD G2 brushless stock motor. Using a sturdy 1-piece can with cooling openings and a fixed timing endbell, the motor is ideal for sanctioned racing classes. Pre-soldered 3.5mm bullet-type connectors make for plug & play ease and a high-precision balanced rotor guarantees smooth and linear power output. The sensored motor is available in a range of windings including 6.5T and 8.5T modified as well as 10.5T to 25.5T stock variants.
Yeah Racing have introduced their new aluminium motor fan mount with 40mm Tornado fan unit. Machined from black anodised 7075 aluminium and featuring a wire-hiding channel the mount features a set screw to tighten down the clamp on the motor can and to lock it at the desired angle. The mount comes including a 40mm Tornado fan but it can also accommodate smaller 30mm units.
Made for Muchmore’s line of Fleta ZX modified motors is the V2 12.0x5x23.0mm optional rotor. Named Modified Maximum Mild, Muchmore’s smallest diameter and shortest modified rotor yet is best used in 5.5T to 8.5T low-grip off-road or 3.5T to 5.5T touring carpet applications while also excelling on big on-road tracks and in 3.5T 1S on-road racing. The small diameter and short length make for smooth acceleration and braking with exceptional high-speed performance. The rotor comes marked for easy identification and it fits all Muchmore Fleta ZX modified motors.
Yeah Racing have a new high-performance fan unit available, the Typhoon Signal 10 Master Competition. Named after the strongest hurricane level in the Saffir Simpson Scale the 40mm unit is high-voltage compatible, allowing to use it with up to 8.4V input, it is dual ball-raced, comes with highly heat-resistant black silicone wires and a Futaba-style connector.
